Is it possible to have clear arteries and still have angina? Some days I feel Finland other days I am short of breath and have pains or pressure in my chest. I do have nitro tablets which help, but my cardiologist dismissed me from care when my catherization was clear. They suggested being checked for acid reflux which I did. That doctor said my symptoms were not acid reflux. Is this something I should get checked by another heart doctor? I am confused.
